Is there an existing issue for this feature request?

I have searched the existing issues

I’m new to OrcaSlicer, and I noticed something that might confuse other new users as well.

I tried printing a VFA test model with speeds set between 75–250 mm/s, but couldn’t figure out for a long time why the result came out perfect across the entire model.

In the VFA test dialog, you only need to enter the minimum and maximum speeds:

Then it asks whether to apply the settings, which I assumed would be enough to run the test:

So I sliced the model and sent it to the printer — and it printed perfectly at all heights.

It turns out the issue was caused by the filament’s “Max Volumetric Speed” setting, which was limiting the actual print speed. Once I raised that value, the test worked as expected.

Which printers will be beneficial to this feature?

All

Describe the solution you'd like

I think it might help if OrcaSlicer either adjusts or warns about this limit automatically when running VFA tests.

Describe alternatives you've considered
